N2 - As SMOS data have been found to contain much more RFI than expected, methods for detecting RFI in SMOS data have been pursued. This paper describes a method using 3<sup>rd</sup> and 4<sup>th</sup> Stokes parameters for RFI detection in SMOS data. Obvious hot-spots are detected, as well as smaller but still detrimental RFI spreading out over for instance the ocean. It is also shown that detected samples statistically deviate (in Kelvin) more from their surroundings than other samples.
